The Barbados threadsnake (''Leptotyphlops carlae'') is a species of blind threadsnake. It is the smallest known snake species.〔 This member of the Leptotyphlopidae family is found only on the Caribbean island of Barbados. The snake was first identified as a separate species in 2008 by S. Blair Hedges, a herpetologist from Pennsylvania State University.〔Dunham, Will. ''Reuters UK'' (3 August 2008). (See: ¶ 5) 〕 Hedges named the new species of snake in honor of his wife, Carla Ann Hass, a herpetologist who was part of the discovery team.〔Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. ISBN 978-1-4214-0135-5. (''Leptotyphlops carlae'', p. 48).〕 Specimens already existed in reference collections in the London Natural History Museum and in a museum in California, but they had been incorrectly identified to belong to another species.〔 At the time of publication, August 2008, ''L. carlae'' was described as the snake species with the smallest adults in the world. The first scientific specimens taken by the research team were found under rocks in a forest. The snake is thought to be near the lower size limit for snakes, as young snakes need to attain a certain minimum size to find suitable food.〔 ==Description== The average length of ''Leptotyphlops carlae'' adults is approximately 10 cm, (3.9 inches), with the largest specimen found to date measuring 10.4 cm (4.09 inches).〔 The snakes are said by Hedges to be "about as wide as a spaghetti noodle.〔 The photograph above shows ''L. carlae'' on a quarter dollar, a coin with a diameter of 24.26 mm (0.955 inches). ''L. carlae'' is thought to feed primarily on a diet of termites and ant larvae.〔 Threadsnakes are oviparous, laying eggs to reproduce. The female of this snake species produces only one large egg at a time. The emerging offspring is about half the length of the mother.〔 Small species of snake such as ''L. carlae'' have relatively large new-born offspring compared to adults. The offspring of the largest snakes are only one-tenth the length of an adult, whereas offspring of the smallest snakes typically are one-half the length of an adult (see figure below). The tiny snakes produce only one, massive egg—relative to the size of the mother—which may suggest that there is a size limit for snake species below which survival is difficult, for internal physiological or external competitive reasons. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Barbados threadsnake」の詳細全文を読む スポンサード リンク
